Motor-Controller-: common questions

What microcontroller does the Motor-Controller- use?

The Motor-Controller- is built around the STM32G474METx, from the STM32 family.

How many components are on the Motor-Controller-?

70 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Motor-Controller- design files?

From the blessyjeba10c/Motor-Controller- repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the Motor-Controller- design in my own project?

The repository has no license, so all rights stay with blessyjeba10c. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Motor-Controller- without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
